scala.js - Geolocation in scala js -

i have following function in scala.js program:

def geo():unit={   var window = document.defaultview   val nav = window.navigator   val geo: geolocation = nav.geolocation   def onsuccess(p:position) = {    println( s"latitude=${p.coords.latitude}")                // latitude    println( s"longitude=${p.coords.longitude}")              // longitude   }   def onerror(p:positionerror) = println("error")   geo.watchposition( onsuccess _, onerror _ ) } 

i calling function main function. printing longitude , latitude continuously after period of time. wanted print 1 time. not able understand doing wrong here , should make stop printing again , again ?

you can use clearwatch stop watching position observed one, this:

def geo(): unit = {   val window = document.defaultview   val nav = window.navigator   val geo: geolocation = nav.geolocation   var watchid: int = 0   def onsuccess(p:position) = {     println(s"latitude=${p.coords.latitude}")                // latitude     println(s"longitude=${p.coords.longitude}")              // longitude     geo.clearwatch(watchid) // observe 1 position   }   def onerror(p:positionerror) = println("error")   watchid = geo.watchposition(onsuccess _, onerror _) }
